Abstract: A baffle system for use on a plate for mass transfer operations comprises at least one channel 1, the surface 5 of the channel through which a two-phase mixture of liquid and vapour leaves the channel having a plurality of holes 8. A deflector 9 is immediately adjacent to each hole, and the deflector is in line to deflect the two-phase mixture towards one end of the channel 1. A liquid return zone is defined by the space 13 between two channels 1 and 2 laterally adjacent to each other. Disengaged liquid from the two-phase mixture collects in the liquid return zones 13 and passes through slots 10 in the channel sides 3 and 4 to re-enter the channel. The baffle system has an inlet weir 4 which blocks off one end of the or each two-phase channel, so that inlet liquid is fed to the liquid return zones. An outlet weir blocks off the other end of the or each two-phase channel and the liquid return zones. (Figures 2 and 9)

Abstract: A coin testing apparatus (10) comprises a coin passageway, a coin track (13) along which coins pass on their edges through the coin passageway and an inductor (16) adjacent the coin passageway. The inductor is connected in an oscillating circuit (40) so that the inductor (16) produces an oscillating magnetic field in the coin passageway. The frequency of the oscillating circuit is measured using a counter (41). A number representative of the idle frequency is stored in register (44). When a coin passes the inductor (16), the apparatus (10) detects whether the resulting frequency shift corresponds to the shift for an acceptable coin by comparing the difference between the number stored in register (44) and the number stored in counter (41) with a number previously stored in memory (48). The inductor (16) is oblong and has its major axis perpendicular to the track so that the arrangement is sensitive to variations in diameter over a large range of diameters.

Abstract: High-intensity-discharge (HID) sodium lamp has a starting aid comprising a conducting ceramic which is hermetically sealed to and extends through an alumina arc tube at least at one end thereof to form an electrically conducting path. The conducting ceramic is fused to the alumina arc tube and is electrically conductive by virtue of having embedded therein a small percentage of finely divided refractory metal. At least during starting, the conducting ceramic is electrically connected through a resistor to the opposite lamp electrode and, as a result, on application of energizing potential, a glow discharge is established between an arc-tube-interior portion of the conducting ceramic and the adjacent electrode to ionize the atmosphere within the arc tube and facilitate lamp starting.
